SPECIFICATION forming part of Letters Patent No. 620,125, dated February 28, 1899.

' Application led .Tune 16, 1898. Serial No. 683.606. (No model.)

To LZZ whom t may concern:

Be it known that we, WALTER P. HATCH, a resident of the borough of Manhattan, inthe city, county, and State of New York, and FREDERIC W. HILLARD, a resident of Tottenville, in the county of Richmond and city and State of New York, citizens of the United States of America, have invented certain new and useful Improvements in Type-VVriters, of which the following isa specication.

The invention consists in an adjustable supporting-frame, called the adjusting-frame or the supporting-frame, which supports one end of the platen and base-frame of the machine, and in the manner in which the platen and base-frame are attached to the adj usting-frame. The machine is especially designed as a book type-writer, but may be used for other purposes.

Referring to the accompanying four sheets of drawings, which form a part of this speciiication, Figure l is a plan View of the type-` writing machine in position for writing on a book. Fig. 2 is a front view in elevation, showing the book in position to be written on and the machine in position for writing. Fig. 3 is a perspective of the base-frame. Fig. 4. is a perspective of the platen. Fig. 5 is a side View showing the platen resting upon the book and the base-frame tilted backagainst the adjusting-frame with the type-writing machine in the position which it will then occupy. Fig. 6 is a perspective view of the adjusting-frame and parts of the platen and base-frame carried thereby, the platen and base-frame being tilted up. Fig. 7 is a perspective View showing a table with a book in position thereon and a leaf properly held in place by the platen and base-frame for printing, the adj listing-frame and the manner of attaching the base-frame and platen thereto being a modification of the showing in the foregoing gures. Fig. 8 is a side view of Fig. 7, showing in full lines the base-frame tilted back, so as to free the leaf.

The type-Writer carriage is shown conventionally. Y

The platen is shown in dotted lines in the position it occupies when tilted back against the base-frame, and the base-frame is shown in dotted lines in the position which it occupies when resting upon the platen holding a leaf in position for printing.

The type-writer machine proper and the manner of mounting it and moving it upon the base-frame and of moving it with the baseframe form no part of our joint invention. Therefore these parts of the device are shown only in a general way in order to illustrate the position and relations of the parts when all assembled and will not be specifically described.

In addition to t-hev movement of the carriage-frame on the base-frame the carriage is so mounted that it may be rockedthrough -somewhat more than ninety degrees on the carriage-frame independently of the baseframe.- Inorder to prevent the rack from dropping out of engagement with the dog when the carriage isv tilted on the carriageframe, a curved lock is provided, which locks the frame and the carriage together and prevents relative movements of the two as the carriage approaches the vertical position. There is also provided at the rear of the carriage a finger, which is intended to rest upon a bar extending clear across the base-frame when the carriage is turned up to prevent it from turning over, the bottom side up. On the carriage-frame there are also provided two'locks, one at each of the rear corners of the carriage frame, Which when the baseframe, with the carriage, is lifted in the position shown in Figs. 5 and 8 lock the carriage and the carriage-frame together and prevent the carriage from falling back to a position at right angles to the base-frame; but these locks and the nger referred to are not fully described, because they are the sole invention of one of the applicants and not the joint invention of the two.

Referring now more especially to Figs. 1 to 6, it will be lseen that the adjusting-frame is fastened to the table.. This I prefer to do by attaching to the table a suitable base-plate l, which is provided with lugs 2 3, the lug `2 being higher than lug 3. On the lug 2 is mounted a spring-controlled pawl 4 and a segment 5, provided with ratchet 6, with which the `pawl engages. Y Segment 5 is pivoted to lug 2 by a pin or screw 7. Lug 3 is provided with IOO lifting-lever 8, which is pivoted to the lug by pin or screw 7, and has' on its upper end a handle 9.

The adjusting-frame consists of a horizontal bar 10, provided at each end with ears 11 11, pivoted, respectively, to segment 5 and lifting-lever 8 by pins or screws 12 12a. The distance between pivots 7 and 7'L is equal to the distance between pivots 12 and 12, and the distance between pivots 7 and 12 is equal to the distance between pivots 7 a and 12% Hence cross-bar 1 0 will remain horizontal in all positions at which it may be adjusted and each position of the cross-bar will be parallel with all other positions thereof. Segment 5 and lifting-lever 8 constitute links by which the adj usting-frame is supported in position on base-plate 1. By means of the handle 9 the adj listing-frame can be lifted or lowered, and by means of the ratchet 6 and the pawl 4 it can be held at any point, the ratchet and pawl supplying a self-acting stop, which permits the lifting of the frame, but holds it against being lowered, except when the pawl is raised out of the ratchet. Cross-bar 10 is provided with lugs 13 13, which are bored out to receive shaft 14. This shaft is circular, so that it both supports base-frame 15 and platen 16 and also permits them to swing thereon when they are lifted up off from the book.

As shown in Fig. 3, the base-frame is a rectangular frame, and as shown in Fig. 4 the platen is a plate of iron faced with a sheet of rubber and is made of a size slightlylarger than the opening in the base-frame.

The base-frame is provided with two supporting-yokes 17 17, which are grooved to rest over shaft 14 of the ad j usting-frame. Yokes 17 17 are also provided with ears or stops 18 18. With the base-frame thus yoked tothe adjusting-frame the base-frame can be tilted up as shown in Fig. 5, its lower end being supported by the yokes 17 17 which rest upon shaft 14 of the ad j usting-f rame, while the ears or stops of the yokes 18 18 rest against the rear of cross-bar 10, which acts as a rest. The rear of the cross-bar, which acts as a rest, should be set so that the base-frame may be tilted back beyond the perpendicular. The platen is also provided Withsupporting-yokes 19 19, whichare grooved to engage with shaft 14 of the adjusting-frame. The platen cannot be tilted backward unless the base-frame is tilted backward, and then the platen when tilted up will rest againstthe bottom of the base-frame. The supporting-yokes of the base-frame are placed so that they will lie outside of the supporting-lugs of the platen, and the end of the base-frame rests just above the supporting-lugs of the platen when the base-frame andthe platen are in the position for printing.

The platen and the base-frame together constitute the base of the machine. The

platen is the printing-base and helps to support the base-frame, and the base-frame is a supporting-base for the carriage-frame and carriage. One end of the base is, as will be seen, attached to the supporting or adjusting frame, upon which the base is free to be tilted as a fulcrum, and when tilted can be leaned against the cross-bar of the ad justing-frame as a rest.

The construction whereby the platen and the base-frame are yoked to the adjustingframe has the advantage that there is formed a sliding contact, so that when the adjusting frame is moved up and down the base-frame and platen do not follow the consequent lateral movement of the adj usting-frame.

Referring now particularly to Figs. 7 and 8, there is shown a suitable table 50, provided for holding the book 51, which is laid upon blocks 52 52, between the adjacent edges of which the back of the book rests. The adjusting-frame is fastened t0 the table as before by attaching to the table a suitable plate 53, which is provided with lugs 54 54. The adjusting-frame in the form in which it is shown in Figs. 7 and 8consists of two horizontal rods 55 55, rigidly connected to each other by brackets 56 56. The adj usting-frame is connected to the lugs 54 54 by means of links 57 57, which are attached to the lugs and the brackets by bolts 58 58, as in the other IOO catch to hold the frame in anyposition in which it is set. The pawlv permits the rotation of the ratchet-wheel in the direction for lifting the frame, but holds the ratchet-Wheel so that the frame cannot fall back when lifted until the pawl has -first been disengaged from the ratchet-wheel.

The base-frame 61 is made up of four sides riveted together. The platen 62 is a plate of iron faced with a sheet of rubber and made of a size just to fit into the base-frame lengthwise and somewhat wider than the interior measurement of the base-frame. When in position for printing, the sides of the baseframe lie above the edges of the platen. The grooves 63 63 in the supporting-yokes 64 64 of the platen and the grooves 65 65 inthe yokes 66 66 of the base-frame are cut at different angles. This renders it impossible to jar or remove them from theirod when in the printing position or when tilted back against the upper rod 55. The grooves in the yokes 66 6G ofy thebase-frame make an angle with the vertical when the frameiis in printing position.

The platen is provided with a tongue 67, which fits into a notch 68, cut in the adjacent end of the base-f rame to prevent lateral movement between the platen and the base-frame but this feature also forms no part of our joint invention.

The two horizontal rods 55 55 may be IIO brought closer together or placed farther apart, according to the preference of the constructor. Placing them close together, as in the iirst form illustrated, has the advantage that the base-frame may be turned back, carrying with it the carriage and carriageframe, irrespective of the position of the carriage-frame on the base-frame, which is not true in the second form illustrated, and, further, since the supporting-yokes 1717 of the base-frame bear at stops 18 1S against the adjusting-frame there is no chance that the yokes will slip off from the rod of the adj usting-frame with which they engage when the base-frame is tilted backward. O n the other hand, with a heavy type-Writing machine and frame there is some danger that the `weight of the machine may break the supporting-yokes of the base-frame when the rods of the ad justing-frame are brought close together.

In either form of our invention it will be seen that the parallelism of all positions of the ad j listing-frame is insured with every other position thereof. From this it follows that if the parts are properly proportioned to insure the parallelism of any one position of the adj usting-frame With the table-top this parallelism will always be maintained and that if the table-top be level the adjusting-frame will also be level. It will also be seen that the loose connection between the platen and the adjusting-frame formed by the slots in the platen permits a freedom of movement between the two parts, whereby the platen can when lowered on the book rise partly or entirely off the adj usting-frame. The platen will rise partly off the adjustingframe-for instance, at one yoke-if the adj ustin g-t'rame is closely adj usted to the height of the book; but the book is not exactly level, while if the adj usting-frame is not lifted sufficient-ly high the platen when lowered on the book will rest entirely thereon and be raised entirely from off the adjusting frame. Whether the platen has its one end entirely or partly supported by the adjusting-frame or Whether the platen is supported bythe book independent of the adjusting-frame the loose connection above referred to permits the adjusting-frame to hold the platen against lateral displacement and the ready dismounting of the platen. The similar loose connection between the base-frame and the adjusting-frame permits the weight of the baseframe in Writing to be carried entirely by the platen and at the same time permits the adj usting-frame to hold it against displacement, the adj listing-frame forming a pivot for the base-frame and.platen to turn upon when it is desired to raise the latter. This automatic adjustment of the platen and base-fram e vertically in relation to the lift-frame is found to be of importance.
